抄録

The generation of the extremely high pressure gives the very useful effect of the synthesis of a new material. The metal jet that is discharged by the collision of a metal plate and metal block causes the generation. The metal disk that is put on a metal block is accelerated by the detonation of explosive. The ultra high pressure generates with that the jet collide mutually on the central axis of the conical block. Predicting the velocity of the flyer plate the pressure of the jet have been estimated theoretically. The possibility of the generation of the ultra high pressure over 1 TPa is suggested. The velocity measurement of the flyer plate has been tried, to confirm about this possibility. As a result, it is conceivable that the jet have reached the pressure of several hundreds MPa.
